I was going to do the turbo thing, but was talked into the Vortech by a mate the had a similar setup. great on the street, but have gone through 4 8 rib belts now for no apparent reason. alignment is sweet. at $114 NZ bucks a belt it adds up. all belt issues have been at the track. 2.87 head pulley and 7" crank pulley is already up to max head unit capacity.
